I can only answer the second part of your question. As far as attraction goes, polar is not the opposite of nonpolar. Polar in itself has two opposites: positive and negative. Those two are the opposites that attract; a positive region of a polar molecule is attracted to the negative region of another polar molecule.
The fatty acid tails of the phospholipid molecule would reject the polar molecule glucose, as the tails are nonpolar and hydrophobic in nature. Glucose is hydrophilic and would not be compatible with the hydrophobic environment created by the fatty acid tails.
The Cholesterol molecule consists of four planar rings - comprised from 19 carbons - and a side-chain of another 8 carbons and only hydrogens throughout: except at one end is one lone -O- negative 1. That is one throughly non-polar molecule. By the way the planar, non-polar, interior ends of the nucleotide bases make for a totally non-polar interior of the DNA double helix!
An iodine molecule is formed by two 'I' atoms. It implies that the molecule is symmetrical and it is non-polar.
Yes a molecule can be nonpolar when it contains polar covalent bonds, because think about it.if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar
A molecule that is both hydrophobic and polar has a nonpolar region that repels water (hydrophobic) and a polar region that interacts with water (polar). This unique combination of properties allows the molecule to dissolve in both water and nonpolar solvents.
A molecule with a polar and nonpolar region is called amphiphilic or amphipathic. This allows it to interact with both polar and nonpolar substances, making it useful in various biological and chemical processes.
Fatty acids are nonpolar.
The molecule is nonpolar.
No a molecule is a molecule, polar or nonpolar.
Methyl is a nonpolar molecule.
